- Abstract
Attention-deficit/hyperactivity disorder (ADHD) is associated with unexplained impairments on speeded naming of coloured stimuli. These deficits may reflect hypofunctioning retinal dopaminergic mechanisms impairing particularly blue–yellow colour discrimination. Colour perception and rapid colour naming ability were investigated in 14 children with ADHD and 13 healthy peers matched for age, gender, and IQ, using the Farnsworth–Munsell 100 Hue Test (FMT) and the Stroop-Colour-Word test. Children with ADHD committed more errors on the FMT, particularly on discrimination of colours along the blue–yellow axis, and were slower on Stroop subtests involving colour naming. However, the latter deficit was accounted for similarly by blue–yellow and red–green discrimination abilities. Blue–yellow colour perception problems in ADHD contribute to but do not fully explain the observed slowed colour naming.
